Required (Note: Originally the fire blanket was intended to extinquish people on fire. But it is now believed it better for a person on fire to IMMEDIATELY drop and roll. A person with clothing on fire should never run to obtain a blanket. Subsequently fire blankets were recommended for keeping a burned person warm. But it is now considered crucial not to wrap any burned area with a material such as a blanket where additional damage may be caused upon removal. Recently it has been proposed the fire blanket could be used to provide privacy for someone removing clothing as recommended while using an emergency shower. But a shower curtain would be more appropriate. DWT)
